WiTricity is taking its wireless power-transfer technology for a ride.
The company has successfully tested a wireless charging system for electric vehicles (EVs) in cooperation with automaker Nissan.
The testing program was sponsored by the Society of Automotive Engineers (SAE) wireless power task force at the U.S. Department of Energy’s Idaho National Laboratory.
The system leverages WiTricity's magnetic resonance technology to deliver a range of power over distance and through materials — enabling transfer of up to 11 kilowatts, with the ability to scale to 25 kilowatts and higher for next-generation automobiles with higher power requirements.
WiTricity's charger can be deployed as a floor pad in a consumer’s garage, or can be installed below the surface of the pavement to provide wireless charging in public and commercial parking lots. The system operates at very high efficiency of 91 to 94 percent, superior to many wired charging systems that are now on the market, the company said.
The new WiTricity system is designed to work across vehicle brands and vehicle types including all-electric and plug-in hybrid electric vehicle platforms.
WiTricity has announced licensing agreements with Toyota, Delphi, TDK, IHI and BRUSA. The company is also collaborating directly with leading carmakers to drive global standards for wireless charging systems.
"We're thrilled to be announcing this new system and proud to assume the mantle of high-power charging leader. Having engaged with the automakers to comprehend their key requirements, I'm confident in the huge impact WiTricity can deliver for the industry and consumers," said Alex Gruzen, CEO, WiTricity. "EVs have the potential to change transportation in a massive way and simplifying the charging experience is foundational to broad driver adoption. This system will help drivers get power conveniently and efficiently without having to think of plugging in."
